A novel pillared-layer framework with a (52.6)(53.63.73.8) Schl fli symbol, [Mn(H2O)(Htrz)(Hbtc)]n (1), was prepared by the reaction of 1,2,4-triazole (Htrz), 1,3,5-benzenetricarboxylic acid (H3 btc), and Mn Ⅱ salt and structurally and magnetically characterized. It crystallizes in the orthorhombic system, space group P212121 with a=7.1618(5), b=9.0356(6), c=10.9740(13) , V=1292.54(15) 3 , D c=1.799 g/cm3 , Mr=350.15, Z=4, F(000)=708, μ=1.064 mm -1 , and the final R=0.0177 and wR=0.0462 for 2273 observed reflections with I > 2σ(I). The unique octahedral Mn Ⅱ ion in 1 is periodically linked into a two-dimensional (2D) magnetic layer by μ2 -N1 , N4 -Htrz and syn, anti-COO of doubly deprotonated Hbtc 2anion, which is further supported by the phenyl backbone of Hbtc 2ligand to generate a 3D pillared-layer framework. Magnetically, complex 1 displays an antiferromagnetic ordering below 5.0 K due to the cooperative antiferromagnetic couplings mediated by the mixed heterobridges within the magnetic layer.
